Total Weight on Your Vehicle’s Tires
Be sure your vehicle’s tires are inflated to the
upper limit for cold tires. You’ll find these numbers
on the Tire and Loading Information label. See
Loading Your Vehicle on page 322. Then be sure
you don’t go over the GVW limit for your
vehicle, including the weight of the trailer tongue.
Hitches
It’s important to have the correct hitch equipment.
Crosswinds, large trucks going by and rough
roads are a few reasons why you’ll need the right
hitch. Here are some rules to follow:
• The rear bumper on your vehicle is not
intended for hitches. Do not attach rental
hitches or other bumper-type hitches to it.
Use only a frame-mounted hitch that does not
attach to the bumper.
• Will you have to make any holes in the body
of your vehicle when you install a trailer
hitch? If you do, then be sure to seal the holes
later when you remove the hitch. If you
don’t seal them, deadly carbon monoxide (CO)
from your exhaust can get into your vehicle.
See Engine Exhaust on page 138. Dirt
and water can, too.
Safety Chains
You should always attach chains between your
vehicle and your trailer. Cross the safety
chains under the tongue of the trailer so that the
tongue will not drop to the road if it becomes
separated from the hitch. Instructions about safety
chains may be provided by the hitch manufacturer
or by the trailer manufacturer. Follow the
manufacturer’s recommendation for attaching
safety chains and do not attach them to the
bumper. Always leave just enough slack so you
can turn with your rig. And, never allow safety
chains to drag on the ground.
Trailer Brakes
Does your trailer have its own brakes?
Be sure to read and follow the instructions for the
trailer brakes so you’ll be able to install, adjust
and maintain them properly. And because you may
have anti-lock brakes, do not try to tap into your
vehicle’s hydraulic brake system. If you do,
both systems won’t work well, or at all.
